Title: Video signal processing circuit and video recorder using the same
Inventor: FUJIYAMA HITOHIRO
IPC: H04N5/44
Filed: 1998-11-02
Abstract: PROBLEM TO BE SOLVED: To eliminate erroneous video-recording due to wrong selection by a VTR, when the VTR records a video image displayed on a television receiver by comparing respective synchronizing signals from synchronizing separator means and discriminating the coincidence of 1st and 2nd video signals, when the synchronizing signals are coincident. SOLUTION: A video signal, that is received from an antenna 1 and selected by a channel selection circuit 2 of a VTR is given to a synchronizing separator circuit 3, where a synchronizing signal is separated and only a synchronizing signal 12 is obtained. Furthermore, a video signal selected by a channel selection circuit of a television receiver is given to a synchronizing separator circuit 7 of the VTR through input/output terminals 5, 6, where a synchronizing signal is separated, and only a synchronizing signal 13 is obtained. An OR circuit 8 receives the synchronizing signals 12, 13, and an output from the OR circuit 8 is given to an input section B of a monostable multivibrator circuit 9.  A broadcast station matching signal 14 is generated from an output Q of the monostable multivibrator circuit 9, only when timing of the synchronizing signals 12, 13 at L level is matches where the synchronizing signals 12, 13 are at L level in their synchronization timing.
